An amusement park charges $33 for student admission an $57 for adult admission. By 10:00am the park had made a total of $2,982 o

MArishka [77]

Answer:

The number of adults admitted were 28.

Step-by-step explanation:

Given:

An amusement park charges $33 for student admission an $57 for adult admission. By 10:00am the park had made a total of $2,982 on park admissions.

Total sales made up of student tickets $1,386.

Now, to find the adults admitted into the park.

Total sales made up of student tickets = $1,386.

Total sales made up of = $2,982.

Now, to get the sales made of adult tickets by subtracting total sales made up of student tickets from total sales made up of:

$\$2982-\$1386\\\\=\$1596.$

Thus, the sales made of adult tickets is made up of $1,596.

Charges for an adult admission = $57.

Let the number of adult tickets be $x.$

Now, to get the number of adults ticket by putting an equation:

$57 x=1596$

Dividing both sides by 57 we get:

$x=28.$

Therefore, the number of adults admitted were 28.

The only items in a container A are 150 pencils and 725 pens. The ratio of the number of pencils to the number of pens in contai

Norma-Jean [14]

Answer:

Option E) 8000

Step-by-step explanation:

It is given in the question that the number of pencils and pens in a container A are 150 and 725.

Let the number of pens and pencils in container B are x and y.

As per statement " Ratio of the number of pencils to the number of pens is 2:3"

Equation will be $\frac{x}{y}=\frac{2}{3}$

Or $x=\frac{2}{3}y$ ------(1)

Second statement says "If all pens and pencils of container B are placed in container A then ratio of pencils and pens would be 3:5"

Equation will be $\frac{x+150}{y+725}=\frac{3}{5}$

5(x + 150) = 3(y + 725) [By cross multiplication]

5x + 750 = 3y + 2175

5x - 3y = 2175 - 750

5x - 3y = 1425 ------(2)

Now we put $x=\frac{2}{3}y$

$5(\frac{2y}{3})-3y=1425$

$\frac{10y}{3}-3y=1425$

$\frac{10y-9y}{3}=1425$

$\frac{y}{3}=1425$

y = 3×1425

y = 4275

Now we put y = 4275 in equation 1

$x=\frac{2}{3}(4275)$

x = 2850

Now (x + y) = 2850 + 4275

= 7125

Now Total number of pen and pencils in container A and container B

= 150 + 725 + 7125

= 8000

Therefore, Option E) is the answer
